Subject: bug#31796: 27.1; dired-do-find-regexp-and-replace fails to find multiline regexps
Date: Mon, 23 Nov 2020 10:09:38 +0100

The dired-do-find-regexp-and-replace command does not seem to parse the 
regex entered by the user correctly.  If the regex string contains a 
newline character (^Q^J), it seems that the parsing stops there.  At 
least I have seen errors like "unmatched bracket" and the like.

Anyhow, I did not get it to replace multiline text.  I found an answer 
here:


https://emacs.stackexchange.com/questions/30437/dired-search-and-replace-is-throwing-no-results

The solution is to manually invoke dired-do-query-replace-regexp 
(instead of pressing just Q).

However, this solution is hard to discover, because it is unexpected 
that the official regex-replace feature (key Q) contains such a blunder.

- Why isn't the more robust

  dired-do-query-replace-regexp

bound to Q?

- Why not fix the bug in dired-do-find-regexp-and-replace?  It has been 
reported for version 26 already, and it is not a minor issue.  Replacing 
interactively in several files is an **extremely** useful feature, and I 
would not want to do something like that outside of emacs.

Thanks for all the good work going into emacs.

Best,
Andreas

P.S.: Your approach to issue tracking (by email) must be considered 
stone-age by now.  How about switching to GitHub / GitLab or the like?

(Unless you want to keep the bar up, of course.  But this is hardly in 
the spirit of open source.)
